I feel like a lot of success Nintendo gets with their handhelds is directly related to this.
I feel if the original team members made a game it still won't make a difference in comparison to Nintendo's handheld games. I will tell you why, games like GoW and Uncharted do not translate as well on handhelds. Even if Naughty Dog made Uncharted on Vita, the PS3/PS4 Uncharted will always look bigger and better due to the power of the hardware. Of course some people don't mind that and would like to play Uncharted on handheld, this is why Sony has other developers make the game while Naughty Dog concentrate on the consoles. I don't see the problem with this as long as the other developers do a good job, some people actually preffered Ghost of Sparta over GoW3, same with Resistance Retribution. However what Sony are lacking are those games that translate well to handhelds which Nintendo have. NSMB, Mario Kart and Animal Crossing all work well on handhelds. Also Nintendo have exclusive titles made for handhelds like Nintendogs, Brain Age, Pokemon and etc.
Sony will never have something as big as Pokemon, NSMB and Mario Kart so 3DS will outsell Vita no matter what. However Sony should attempt to create new IP that work well on handhelds like Nintendo did last gen with Brain Age and Nintendogs. Maybe Soul Sacrifice could be a new IP that takes things from Demon Souls series as well as Monstwer Hunter to make a great handheld, if this was the case that could be a huge hit that is made for handhelds. Sony have some IPs that translate to handhelds quite good, such as LittleBigPlanet, Gran Turismo, Jak and Daxter etc. So they should make quality sequels to those games on Vita. Of course there are some people that enjoy console type games on Vita so Uncharted and GoW isn't a bad idea on Vita, but it shouldn't be Sony's main focus. What I am saying is Uncharted and GoW mayybe okay as they are top selling IPs, but there is no point wasting resources creating a handheld spin off for Resistance, Killzone and etc, those games are not big sellers on console anyway and the handheld versions will most likely sell worse. Also Sony need to publis 3rd party games and have better marketing campaigns, they need to get games like Layton, Monster Hunter all aboard the Vita. Those are other examples of games made for handhelds.
Here are examples of what games work well on Vita
Uncharted - these types of games work better on consoles however, this is one of Sony's best selling IPs so it gets a pass
GoW - same as above
LittleBigPlanet - translated to handhelds quite well
WipeOut - same as above
Gran Turismo - this could be their killer app, but they need to make sure this time the game is as extensive as the console version with full career mode
Invizimals - this was a new IP sony created last gen for PSP, was a hit in Europe as it was made for handhelds with unique gameplay using AR
Monster Hunter - top seller for PSP
Layton - Big seller there is a reason Nintendo helps with publishing with this IP, these types of games work well on handhelds
Jak and Daxter- platformers work well on handhelds, Daxter was one of PSP's best sellers
Eyepet - can work well on a handheld, similar to nintendogs, they can use AR, mic as well as touch to interact with the pet
Buzz - quiz game, learning games, brain training and etc work well on handhelds, Sony need their own Brain Age, Picross.
Sony should look at Pokemon, Nintendogs, NSMB, Mario Kart, Monster Hunter, Dragon Quest IX, Animal Crossing, Brain Age, Layton and etc. These games have many things in common, simplicity as in they are accessible to casuals. The games would always work better on handhelds due to the nature of the games. The games are pick up and play, don't have huge narrative/story and don't rely on graphics to shine. There is some addictive nature about the games such as the trading and collecting in Pokemon, the co-op in Monster Hunter and etc. The gameplay is simple yet it can be deep, Pokemon battles are simple and anyone can play but you can get deep into it and have crazy strategies. Sony need to create a IP like these to be successfull, unfortunately Sony doesn't have many IPs that work like this right now (only LittleBigPlanet, WipeOut, Gran Turismo, with only GT being the big seller out of those). Where as Nintendo have Mario, Mario Kart and Animal Crossing, they get 3rd party titles like Dragon Quest, Monster Hunter, Layton, Phoenix Wright and and etc that work well with handhelds. They create new IPs for handhelds exclusively such as Pokemon, Brain Age and Nintendogs.
So in conclusion this is what Sony need to do
- Don't make console spin off of games that rely on narrative, graphics and immersion, of course a few here and there is okay such as Uncharted and GoW, but stop doing this with every PS3 IP, cause people will just say I'd rather play on the big screen
- Look at Sony's current IP's they hold and release quality sequels for the Vita, LittleBigPlanet, Gran Trurismo, Jak and Daxter all would work on handhelds, they should be quality sequels with full career mode for GT, full creator for LittleBigPlanet. The PSP versions of both those titles were lacking full feature set.
- Create new IP that are simple yet addictive, pick up and play and work well on handhelds, Invizimals is a good example, but they should create more such as say a Demon Soul's clone except make it more pick up and play like Monster Hunter.
- Get more 3rd party support for games that work well on handhelds, Layton, Dragon Quest, Monster Hunter, Phoenix Wright, Torchlight, Lumines, Sonic, Burnout and etc work well on handhelds.
- More bigger marketing push, Nintendo did this with NSMB, Dragon Quest, and etc.
